PROBLEM TO BE SOLVED: To provide a hybrid power generating system that can prevent backflow of fuel gas from a combustion chamber at the actuation time of MGT before start of a cooperative operation.SOLUTION: A hybrid power generating system has an exhaust fuel gas supply line 27c having an exhaust fuel gas on-off valve 32 and an exhaust fuel gas flow amount adjusting valve 33, an oxidized gas supply system 70 having an oxidized gas flow amount adjusting valve 71, an actuating oxidized gas supply line 76 which is branched from the oxidized gas supply system 70 at the upstream of the oxidized gas flow amount adjusting valve 71, has an actuating on-off valve 73 and supplies oxidized gas to the combustion chamber when MGT 50 is actuated, and a fuel gas backflow preventing line 78 which is branched from the oxidized gas supply system 70 at the upstream of the oxidized gas flow amount adjusting valve 71, connected to the exhaust gas supply line 27c, has a backflow preventing on-off valve 79, and supplies the oxidized gas to the combustion chamber through the exhaust fuel vas supply line 27c when MGT 50 is actuated. |
